. >> reporter: so this is a ballot for alameda county, the city of berkeley, there's four different cards, there's 39 different things to vote on, there's 93 choices including -- well, here's the man running for mayor who calls himself da mayor and he is nextzachary running wolf and tom bates who is the mayor. 93 separate choices you have to make. so be prepared to spend some time here. >> i have already pretty well made my mind up on the propositions and the candidates. >> reporter: that's a smart way to avoid spending your entire afternoon down here. so in alameda county it is 52% who will either write in now or mail their ballot in. in california, it's about 50/50. and who does it help? well, it used to be republicans because they were generally ones that were a little more well off they could go away and they would send in an absentee ballot but now as you heard this gentleman say and we talked to, he might be working two jobs. so he's a democrat and it's hard to tell who will benefit. in oakland, mike sugerman, cbs 5. >>> as campaign 2012 heats up, cbssf.com is holding a presidential forum.
